A black hole is nothing but empty space. Instead, it is a large number of objects packed in a very small space – think of a star ten times larger than the Sun constricted in an area about the size of New York City. The result is a field of gravity so powerful that nothing, not even light, can escape black holes was predicted by Einstein’s theory of relativity, which showed that when a giant star dies, it leaves a small, dense spine of relics. When, the size of the spine is more than three times the size of the Sun, statistics show, and gravity exceeds all other forces and produces a black hole.
Once a black hole has formed, it can continue to grow by absorbing more substances. Any black hole will keep absorbing gas and star dust in the surrounding area. This growth process is one of the possible ways to build the largest black holes, although the formation of large black holes is still an open field of research. A similar process was proposed for the formation of medium-density black holes found in globular clusters. Black holes can also interact with other objects such as stars or other black holes. This is thought to have been important, especially in the early growth of large black holes, which may have formed from the combination of many small particles.
Why Scientists still have no clue about the Black hole
Scientists cannot directly detect black holes through binoculars that receive x-rays, light, or other types of radiation. However, we can detect the presence of black holes and study them by discovering their effect on other nearby objects. If a black hole passes through a cloud of interstellar matter, for example, it will drag the matter into a process known as accretion. The same process can occur when a normal star passes near a black hole. In this case, a dark hole can pierce the star as you pull it toward you. As the magnetic field accelerates and heats up, it emits x-rays from space.
Just as Scientists cannot see dark holes the way they can see stars and other celestial bodies. Instead, astronomers must rely on the discovery of black holes that emit radiation as dust and gas are drawn into dense organisms. Recent findings provide compelling evidence that black holes have a profound effect on the environment – emitting powerful gamma rays, devouring nearby stars, and promoting the growth of new stars in some areas while disrupting others.
But large black holes, in the center of the galaxy, may be covered with thick dust and surrounding gas, which could prevent significant pollution. Sometimes, as the matter is dragged into a dark hole, it emerges from the horizon and is thrown out, rather than being drawn into the womb. Light jets of fast moving objects are created. Although the black hole is invisible, these powerful planes can be viewed from afar.
Why the Science community has questions about knowing the mystery of the Black hole
As a scientific partnership, the purpose of EHT is not only to prove the existence of black holes, but also to understand the physics of black holes and their surroundings. There is a lot of indirect evidence from various astronomical studies showing that black holes exist, including the investigation of nearby objects under the gravitational pull of the black hole. These conditions are well defined by the General Theory of Relativity (GR). It was a direct view of the surrounding area around the black hole — the horizon — that had never been achieved, until now. With the release of the first results in April 2019, EHT has filled an important gap in our technical knowledge.
Black holes are a basic theoretical laboratory that describes how the Universe works on both the largest and smallest scales (e.g., GR and Quantum Physics). While each of these theories works well in its own dominion, physicists do not yet understand how to create a single visible theory that could be universal and, therefore, explain the physics of black holes in detail. With the effects of EHT, scientists are able to directly determine the atmospheric conditions at the black hole boundary.
Astronomers have discovered some black holes, too, by looking at the confusing patterns of unfortunate stars around them. They have seen dark holes in the light emanating from the object as it penetrates into the invisible depths, a process so powerful that the particles glow brightly. And they have felt it in the arteries of time, gravitational waves blowing through the space when two black holes collide. Dark holes, it turns out, are ubiquitous, in the center of many galaxies and are scattered everywhere, and come in a variety of sizes. (Some even seem so large, it is thought they should not be.) Earlier this year, astronomers discovered a well-known black hole very close to Earth at a distance of about 1,000 light-years, almost near our doors by cosmic steps, the star visible to the naked eye. . The variety of acquisitions is best for something that is best known for its emptiness.
That black hole nearby is not a threat to Earth. No known black hole. If there is, we benefit from their presence. Astronomical explosions producing black holes also spit out nutrients such as carbon, nitrogen, and oxygen into the atmosphere. The collision of black holes with neutron stars helps to disperse the heavy elements, such as gold and platinum. These elements make up our Earth, as well as ours.
